The 49ers have taken a wait-and-see approach when it comes to their pending free agents, raising questions as the new regime approaches its second offseason.

Of all their notable players unsigned beyond 2017, only nickel cornerback K’Waun Williams was given an extension midseason. And he was brought in by the new leadership on a one-year deal in February. None of former general manager Trent Baalke’s holdovers, which include starters Carlos Hyde, Eric Reid, Daniel Kilgore and Dontae Johnson, have been given new contracts.

Now that San Francisco is on a bye week, coach Kyle Shanahan and the front office have time to evaluate which players might be worth bringing back after examining their 10-game samples. And there are players Shanahan wants back.

“We talk a lot about where we see these players, and a lot of the guys here I know for sure that are guys that I want back here. I definitely have seen enough of that to realize that,” Shanahan said.

The 49ers entered the year with more than half the roster turned over after Shanahan and GM John Lynch inherited the 2-14 club under Baalke and Chip Kelly. They moved on from notable veterans like NaVorro Bowman, Ahmad Brooks, Quinton Dial, Antoine Bethea, Torrey Smith and others, which would indicate the team may be willing to turn over the roster at a similar rate in the spring.

After all, the 49ers are 1-9 and appear likely to land one a top-three pick in the NFL draft for a second consecutive year.

“There is a business side to all of that stuff,” Shanahan said. “There is a market and things like that. So, you’ve got to be smart for your organization, for the player, and for the future of how we balance things. But, a lot of our free agents that are up, I’m not going to speak about any of them individually, but there are definitely a number of guys that we haven’t obviously redone yet but they have shown that they are guys that we want around.”

San Francisco could have as much as $100 million in cap space to work with when the new league year begins in March – before quarterback Jimmy Garoppolo is given a new deal or the franchise tag worth some $25 million for 2018.

The team has flexibility – and six more games they could use to evaluate which players they’d like to bring back.
